I have 1 miner that will not finish the boot sequence. it just keeps flashing the 7th and 8th leds. i have turned it off for several hours and tried it again still no luck.
Is that batch 1 or 2? There was a bug in early batch 1 boards that was fixed half way through batch 1.
Edit: Before someone asks, the bug was due to new behavior in the revision 2 ASIC chips and was fixed (a workaround) with new firmware.
